Users Instructions (Provisional)
HB3300-01
The Acetone Vaporiser is specifically designed for
the rapid and permanent mounting of the
membrane filters used for sampling and analysing
asbestos fibres. The unit is compact and portable
for site or laboratory use and takes just two
minutes to reach operating temperature.
The instrument utilises a very small
amount of acetone and takes just five seconds to
mount each filter. The simple and fast operation
allows it to be transported to site to reduce the
time taken to obtain results from asbestos
removal operations. The use of this type of
instrument is documented in Methods for
Determination of Hazardous Substances (MDHS)
39 &100, “Asbestos fibres in air”, published by
the Health and Safety Executive in the UK. The
document also covers sampling of asbestos and
may have equivalents under local health and
safety rules.
The instrument uses the Acetone - Triacetin, hot block method. If using the Acetone Vaporiser
for the first time, practise by using unused or discarded filters to gain proficiency.
WARNING
Acetone is highly flammable, do not breathe vapour, do not smoke, keep away from
sources of ignition, use only in a well ventilated area, miscible with water.
Sequence of Operations.
1. Plug into mains power.
The unit operates on 240 V, or 110 V a.c. depending which model has been ordered.
The amber neon lamp is lit, indicating power on.
After approximately one minute the green neon lamp will light, indicating that the unit is ready
for use.
N.B. The green neon lamp will alternate between being lit and off. This is normal, and the unit
can be used in this mode.
2. Place a glass slide and filter on to the slide platform.
The slide platform can be adjusted, allowing the distance from vapour outlet to be set by the
user.
3. Draw approximately 0.3 - 0.4 ml of Acetone into the syringe.
4. Insert the syringe into the hole in the top plate.
5. Inject the Acetone at a slow steady rate whilst holding the syringe firmly in place.
6. After vapour discharge has occurred, remove the syringe.
7. Withdraw the glass slide from the platform.
The filter should now be clear. If not, or it is only partially cleared, repeat steps 3 to 6.
8. Wait a few minutes for the Acetone to evaporate.
9, Using a micro pipette or dropper to apply a drop of Triacetin to the centre of the cleared filter.
10. Cover the filter with a cover slip.
11. Place the slide on to the heater pad and leave for approx. ten minutes.
The filter can now be analysed / counted.
WARNING

heater pad.
